Samsung SDI said it was on target to launch mass production of all solid state batteries (ASSBs) in 2027.
The company released a battery production ‘road map’ ahead of InterBattery 2024, a three day international battery exhibition in Seoul.

ASSBs are regarded as a safer and lower cost alternative to lithium ion widely in use today with their solid electrolyte helping to reduce fire risk. They are expected to become the leading battery type in the global BEV industry.
CEO Choi Yoon-ho said in a statement: “Our preparations for mass producing next generation products such as ASSB are well under way as we are set to lead the global battery market with our unrivalled ‘super-gap’ technology.”
The company completed construction of a pilot ASSB production line last year in Suwon. It produces high density (900Wh/litre) battery prototypes for evaluation ahead of full production. The company said this was a 40% jump in energy density compared with its P5 prismatic battery.
Samsung SDI was also focused on developing prismatic batteries which can be charged from 8% to 80% in nine minutes with commercial production scheduled for 2026, and also extended life batteries with a 20 year life cycle later in the decade.
Samsung SDI said its cell to pack (CTP) design should cut the number of battery pack components by 35% and reduce weight 20% compared with the current P5 pack.
Earlier this year, the company was reported to be preparing to produce 4680 cylindrical cells to help meet growing global demand.
